Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.
Parenchymal changes of the lung can often be evaluated adequately without the use of intravenous contrast. CT pulmonary angiogram: 20 ml [notes 2] 17 ml [notes 2] 15 ml [notes 2] Minimal amount when using specific low-contrast protocol. [notes 2] CT of abdomen: Overall: 70 ml [11] 60 ml [11] 55 ml [11] Liver: 55 ml [notes 3] 45 ml [notes 3] 40 ...
In addition to the use of intravenous contrast, ... abdomen and pelvis CT 9.9 [185] 12 [185] ... (especially for the diagnosis of appendicitis). ...
Computed tomography of the abdomen and pelvis, performed as a contrast CT, here presented as a volume rendering, specifying the scan range and field of view (FOV). It shows normal anatomy, with no injuries. The subject is a 21 year old male who had blunt trauma to the upper abdomen during motocross.
Normally, epiploic appendages cannot be seen on CT scan. [4] After cross-sectional imaging and the increased use of abdominal CT for evaluating lower abdominal pain, EA is increasingly diagnosed. Pathognomonic CT scan data represent EA as 2–4 cm, oval shaped, fat density lesions, surrounded by inflammation. Contrasting with diverticulitis ...
Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. [1] Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. [2] It is taken by mouth or used rectally. [3]
A CT scan demonstrating acute appendicitis (note the appendix has a diameter of 17.1 mm and there is surrounding fat stranding) A fecalith marked by the arrow that has resulted in acute appendicitis. Where it is readily available, computed tomography (CT) has become frequently used, especially in people whose diagnosis is not obvious on history ...
Abdominal and pelvic ultrasounds are critical to rule out common causes of RUQ pain such as cholelithiasis, cholecystitis, and abdominal/pelvic abscesses. Computed tomography (CT) scan should be obtained in the case that the clinical suspicion for appendicitis is high. In cases of Fitz-Hugh–Curtis syndrome, the CT scan may show increased ...
